SCP-5341
Object Class: Keter
SCP-5341 is a closet made with two brass handles and an unknown species of wood. During the day, the doors are locked and cannot be opened. D Class have been ordered to open the door, all of which have failed. One D Class was ordered to use a drill, in an attempt to make a hole through the door. The hole reached 12 feet long before the D Class gave up.
During night, the doors are unlocked, allowing anyone of any strength to open the door. This was accidentally discovered when a D Class managed to open the door, which Dr. Bright shortly realized it was night. When the doors are opened, anyone who touches the handle(s) receive a memetic effect, making them close the door immediately. Those who open the door are considered to be SCP-5341-2. Security footage and interrogations have shown the closet to be endless.
Two D Class were given radios, and ordered to go into the closet. After 3 minutes and 34 seconds, the radios lost connection, and the D Class bodies were thrown out of the closet shortly after; both bodies were mutilated and dismembered horribly.
SCP-5341-2, after 2-12 hours, will attempt to open the doors once again. Upon successfully opening the doors, 30-35 instances of SCP-5341-3 leave the closet doors. At this point, the doors can be opened at any time.
SCP-5341-3 are short hairless creatures, which have similar features to those of a standard monkey. SCP-5341-3 also have teeth and claws that have been proven to be harder than diamond. SCP-5341-3 is exceptionally strong, able to break through steel without strain. During a containment breach, all staff and D-Class are required to stay at least 1 mile away from the facility in an evacuation shelter.
An autopsy, ordered by the 05 Council, showed SCP-5341-2 to have standard monkey organs, however, the blood was acidic, and three organs were special, as they are not in any animal on Earth.
